Depending on how you define it, 200+ might be overkill, but I think that "clock" service on most of the major routes and significant north-south connectivity without forcing a mode shift (namely plugging the hole with buses). The main problem, at present, is that you have two ways to do that and both involve major time-killers (Tehachapi Pass is beautiful but slow, and so is the Coast Line).Honestly, CalTrans and my legislature should put up or shut up when it comes to Amtrak California. California should have 200+ Intercity train trips per day including a handful of overnight trains. I'm ok with paying a little extra in taxes if it means we have an intercity rail network to rival countries like Poland. And that's something that most people would be fine with if someone made the case for it.
A pair of north-south overnight trains (one on each line) would be nice. But it's got practical issues in both cases. I guess the question is what the economics of a "baseline" overnight train with a significant complement of sleepers (the Spirit of California was notably mis-equipped...it had two sleepers that apparently had a tendency to sell out and a batch of coaches that went empty for much of the route; anecdotally, the train seems to have needed another few sleepers since there are only so many pax who are going to willingly go overnight in an Amfleet I) and a cafe.
